Abstract

The invention discloses a jacking device for disc-shaft flange assembling and an assembling method thereof. The jacking device for disc-shaft flange assembling comprises high strength bolts; the high strength bolts are in threaded connection with a shaft end nut flange after penetrating through a hydraulic cylinder positioning block and a disc-shaft flange platen in sequence; one end face of the disc-shaft flange platen makes contact with one end face of a hydraulic cylinder; and the other end face of the hydraulic cylinder makes contact with the hydraulic cylinder positioning block. According to the jacking device for disc-shaft flange assembling and the assembling method thereof, the combined entire jacking device is of a hollow structure; an oil pipe connector of an oil pressure expansion tool can be stretched into and fixed into a center oilhole on a shaft end of a dynamometer; the jacking device under the state of preinstalling and working plays a limiting role in the hydraulic cylinder, doesn't interfere with an oil inlet and the connector of the hydraulic cylinder, is applicable to the installation of the dynamometer shaft end and the corresponding disc-shaft flange, and effectively solves the problem that the disc-shaft flange installed by manpower is small in the magnitude of interference and bad in installation.

Description

technical field [0001] The invention belongs to the technical field of conical interference fit hydraulic assembly, and in particular relates to a jacking device and an assembly method for assembly of disc shaft flanges. Background technique [0002] Conical interference fit is a connection method that can be disassembled repeatedly, reliable in connection and does not require screw fastening. During the assembly process, according to the calculated assembly oil pressure, oil is pressed to the joint surface to form an oil film, and the disc shaft flange is manually pushed to the limit position. Finally, apply the pressing force until the stroke of the flange of the disk shaft reaches the limit of the axial displacement, then maintain the axial pressing force for 15-30 minutes and then drain the oil. In addition to high requirements on the processing precision of the joint surface, the connection has the advantages of good connection reliability, simple structure, long mainte...
